This application is a Continuation Application of pending U.S. patent application Ser. No. 13/847,517 filed on Mar. 20, 2013.

FIELD OF THE INVENTION

The present invention relates generally to computer service management technologies and tools, and more particularly to a system and method of updating progression of performing computer system management.

BACKGROUND

In computer service management, there is a demand for accurately managing and tracking changes that occur to computer systems. A great amount of system outages are due to changes in the computing environment, where the changes are not planned, authorized, or mistakenly implemented. Since the computer systems are largely managed by processes, there is always the possibility of human errors causing system outages.

All currently known solutions to the computer service management are related to processes and access restrictions. For example, if a process states that a change authorization or work record is required before system properties are adjusted, it is the administrator's responsibility to ensure the change authorization or work record exists. In another example, any user other than a super user has restricted access to a computer system; in this case, it is the super user's responsibility to ensure the process is fulfilled.

SUMMARY

In one aspect, a method for updating progression of performing computer system management on a managed computer system is provided. The method comprises receiving, by an operating system daemon of the managed computer, a log on of a change implementer.

DETAILED DESCRIPTION

FIG. 1 is a diagram illustrating service management system 100 for updating progression of performing computer system management, in accordance with an exemplary embodiment of the present invention. In this exemplary embodiment, service management system 100 comprises managed computer system 110 and change and configuration management system 120. Change and configuration management system 120 is on at least one managing computer system. In the exemplary embodiment shown in FIG. 1, change management system 121 and configuration management system 123 are two primary components of change and configuration management system 120. Change requests on managed computer system 110 are managed by change owner 140 through change and configuration management system 120. On change management system 121, change owner 140 creates, approves, and authorizes the changes for managed computer system 110. Change owner 140 manages records of the change requests on change management system 121. The records of change requests include information about which configuration items (CIs) on managed computer system 110 are to be changed. Within each of the change requests, there are one or more tasks. Configuration management system 123 is a database that stores information of configuration items (CIs) of managed computer system 110.

Change implementer 130 modifies managed computer system 110. Managed computer system 110 comprises OS daemon 115. OS daemon 115 monitors commands entered by change implementer 130. Monitoring commands uses known art, for example the audit subsystem for IBM AIX®, the event registry in Microsoft Windows®, or other similar systems for other platforms. OS daemon 115 sends commands and data to change and configuration management system 120, and receives information from change and configuration management system 120. Managed computer system 110 and change and configuration management system 120 communicate information of the change requests, information of tasks within each of the change requests, and actual start and stop times of the tasks and/or change requests being implemented by change implementer 130.

In the exemplary embodiment, OS daemon 115 and change and configuration management system 120 interpret commands entered by change implementer 130 of managed computer system 110, and use information of the commands and information of managed computer system 110 (for example, including the userid of the person who logs onto managed computer system 110, the hostname or IP address of managed computer system 110) in combination with the current date and time to automatically populate actual start and stop times for a change implemented by change implementer 130 of managed computer system 110.

In service management system 100, the planned changes or change requests on managed computer system 110 are created, approved, and authorized on change and configuration management system 120 by the change owner 140. Thus, service management system 100 ensures no damaging or disruptive commands can be issued against managed computer systems 110 unless work requests for the changes have been generated, approved, and authorized.

In FIG. 1, for the purpose of demonstration, only one managed computer system (managed computer system 110) is shown in the exemplary embodiment of service management system 100. It is apparent that service management system 100 may comprise multiple managed computer systems. It is also apparent that service management system 100 may comprise one or more change and configuration management systems.

FIG. 2 is a flowchart of service management system 100 shown in FIG. 1 for updating progression of performing computer system management, in accordance with an exemplary embodiment of the present invention. At step 201, change implementer 130 logs onto managed computer system 110 to perform a change. At step 203, OS daemon 115 on managed computer system 110 captures current date and time. The current date and time are based on the internal clock of managed computer system 110 or a call to a global clock system such as NTP (Network Time Protocol).

At step 205, OS daemon 115 on managed computer system 110 sends information about change implementer 130 and managed computer system 110 to change and configuration management system 120. In the exemplary embodiment, the information about change implementer 130 and managed computer system 110 includes the userid of change implementer 130 who logs onto managed computer system 110 and the hostname or IP address of managed computer system 110. For example, to send the information, OS daemon 115 uses commands “send userid <userid>”, “send hostname <hostname>”, and “send ip address <ip>”.

At step 207, change and configuration management system 120 searches matching CIs (configuration items) of managed computer system 110. The CIs (configuration items) of managed computer system 110 are stored on configuration management system 123 on change and configuration management system 120. Change and configuration management system 120 searches CIs (configuration items) of managed computer system 110 based on the hostname or IP address of managed computer system 110.

At step 209, change and configuration management system 120 searches a change request that is associated with the CIs of managed computer system 110 and has valid status, for example status of “in progress” or “scheduled”. The change request may also be searched by using instructions, summary, or details associated with managed computer system 110.

At decision block 211, change and configuration management system 120 determines whether the change request is found. In response to not finding the change request (No branch of decision block 211), at step 213, OS daemon 115 on managed computer system 110 displays a waning. For example, the warning notifies change implementer 130 that no change request is found. In other embodiments, OS daemon 115 may redirect change implementer 130 onto change and configuration management system 120 to check status of the change request that change implementer 130 is expecting to work on.

In response to that the change request is found (YES branch of decision block 211), or in response to that OS daemon 115 displays a warning at step 213, change implementer 130 enters commands at step 215. The commands are either implementation commands such as “installp websphere” or interaction commands such as “start task n”.

In response to receiving the commands from change implementer 130, OS daemon 115 on managed computer system 110, at step 217, sends the commands with the current date and time to change and configuration management system 120. For example, to send the commands entered by change implementer 130 with the current date and time, OS daemon 115 uses the commands “send command entered”, “send date <current date>”, and “send time <current time>”.

In response to receiving the commands sent by OS daemon 115 at step 217, change and configuration management system 120, at step 221, matches the commands to one or more tasks. The one or more tasks (for example, installing Websphere®, DB2®, and then some application logic) are within the change request. The one or more tasks are implementation tasks that require commands to be run on managed computer system 110. Within one of the one or more tasks there are a series of commands (for example “installp websphere”) or key words associated with the one of the one or more tasks; entering commands or keywords by change implementer 130 signals that the one of the one or more tasks has started or is completed. At this step, change and configuration management system 120 searches implementation tasks to find one or more tasks that are either owned directly by change implementer 130 or the group to which change implementer 130 belongs. Change and configuration management system 120 uses these commands to determine which task or tasks are currently being worked on. One or more tasks may be found in the change request. At this step, change and configuration management system 120 checks whether the commands match the one or more tasks. If the commands do not match the one or more tasks, change and configuration management system 120 determines that the commands are destructive or incorrect commands are run. In other embodiments, in response to determining that the commands do not match the one or more tasks change and configuration management system 120 automatically generates an incident ticket for further follow up.

At decision block 223, change and configuration management system 120 determines whether the one or more tasks are found. In response to determining that the one or more tasks are found (YES branch of decision block 223), change and configuration management system 120, at step 225, updates the actual start and stop times of the one or more tasks. At this step, change and configuration management system 120 determines scheduled start and stop times at which the tasks are expected to be executed. If a command matches one of the one or more tasks and furthermore matches a command starting the one of the one or more tasks, the current start date and time are automatically populated into actual start date and time of the command. A similar method is used for populating the actual stop time at the end of the one of the one or more tasks.

In response to determining that the tasks are not found (No branch of decision block 223), change and configuration management system 120, at decision block 227, determines whether an incident ticket is requested by change implementer 130. In response to determining that the incident ticket is requested by change implementer 130 (YES branch of decision block 227), change and configuration management system 120 sends the request for the incident ticket to change owner 140 for change owner's review at step 249.

In other embodiments, in response to determining that the tasks are not found (No branch of decision block 223), change and configuration management system 120 may send a warning to change implementer 130. If no task is found, change and configuration management system 120 determines that the command has no bearing on the change request. In either case, the command is copied to a log entry of the change request.

In response to completion of the change implemented by change implementer 130, at step 219, OS daemon 115 logs off change implementer 130 from performing computer system management on managed computer system 110. In response to that OS daemon 115 logs off change implementer 130 from performing computer system management, or in response to determining that the incident ticket is not requested by change implementer 130 (NO branch of decision block 227), at step 229, change and configuration management system 120 marks the change request as completed.

In other embodiments, change and configuration management system 120 determines whether a scheduled stop time of a task is reached. In response to determining that the scheduled stop time of the task is reached, change and configuration management system 120 may send change implementer 130 a warning (for example, “back out the change now” or “running out of time”), automatically log out change implementer 130, cancel the change request, or mark the change request as “failed”.

In other embodiments, OS daemon 115 or change and configuration management system 120 allows change implementer 130 to override the automatic detection of an implementation task by using a set of key words. For example, the keywords includes “start task n” (which signals that the change implementer 130 starts task n), “end task n” (which signals that the change implementer 130 stops task n), “done” (which signals that a current task is complete), and “fail change” (which marks the change request as failed). OS daemon 115 sends to change and configuration management system 120 the keywords entered by change implementer 130 using commands, for example, “send start task n” and “send end task n”.

In other embodiments, in response to that a task is started, change and configuration management system 120 detects status of the task in the change request, and changes the status of the task during the progress of implementing the task. For example, change and configuration management system 120 marks the status of the task from “waiting to start” to “started” and from “started” to “completed”.

In other embodiments, OS daemon 115 on managed computer system 110 receives information from change and configuration management system 120. For example, OS daemon 115 receives information by using commands: “receive change ID” and “receive task list”.

Referring to FIG. 2, change owner 140 creates a change request at step 241. Change owner 140 creates the tasks within the change request at step 243; each of the tasks has scheduled start and stop dates/times. At step 245, change owner 140 authorizes the change request and saves the change request on change management system 121 which is one of primary components of change and configuration management system 120. Further referring to FIG. 2, change owner 140 views updated task information on change management system 121 at step 247.

FIG. 3 is a diagram of a computer device hosting managed computer system 110 or change and configuration management system 120 on a managing computer system, in accordance with an exemplary embodiment of the present invention. It should be appreciated that FIG. 3 provides only an illustration of one implementation and does not imply any limitations with regard to the environment in which different embodiments may be implemented.

Referring to FIG. 3, the computer device includes processor(s) 320, memory 310, tangible storage device(s) 330, network interface(s) 340, and I/O (input/output) interface(s) 350.

For example, on a computer device hosting managed computer system 110, one or more computer program(s) 333 include OS daemon 115 (shown in FIG. 1). In the exemplary embodiment, on a computer device hosting the managing computer system, change and configuration management system 120 (including change management system 121 and configuration management system 123, both shown in FIG. 1) resides on one or more computer-readable tangible storage device(s) 330. In other embodiments, change management system 121 and configuration management system 123 may reside on two separate computer devices, respectively.
